This
activity
requires
construction
of
a
simple
salinity
tester.
Students
will
create
their
own
calibration
scale
during
this
experiment,
and
look
at
the
change
in
salinity
that
would
arise
if
freshwater
was
suddenly
dumped
into
the
ocean.
Materials
needed
for
this
investigation
include
a
DC
mill
ampere
meter,
2
D-cell
batteries
and
holder,
bronze
sheeting,
#18
solid
wire,
salt,
deionized

This
self-paced,
interactive
tutorial
guides
learners
through
the
decision-making
process
in
locating
data
that
will
enable
the
identification
of
tabular
icebergs,
including:
selecting
the
appropriate
satellite
orbit,
and
identifying
the
optimal
solar
and
infrared
wavelength
values
to
discriminate
between
water
and
ice
in
remotely-sensed
images.

This
self-paced,
interactive
tutorial
enables
learners
to
identify
and
measure
iceberg
size
from
remotely-sensed
satellite
images.
Two
techniques
are
explored:
the
geometric
shape
method,
which
provides
a
rapid
rough
estimate
of
area;
and
the
pixel
count
method,
which
employs
special
software
to
measure
the
size
more
accurately.

In
this
learning
activity,
students
compare
polar
data
from
the
Arctic
and
Antarctic,
explore
Earth?s
albedo
and
its
effect
on
arctic
sea
ice,
and
examine
graphed
data
and
scientific
visualizations
of
remotely-sensed
satellite
data.
Readings
related
to
the
shrinking
ice
cap
and
albedo
are
linked
to
this
lesson.
This

In
this
self-paced
tutorial,
learners
trace
the
feedbacks
in
the
Earth
system
that
are
responsible
for
the
Arctic's
sensitivity
to
global
climate
change
impacts.
Both
graphical
data
sets
and
scientific
visualizations
are
evaluated
for
evidence
for
decreasing
sea

cover
and

This video provides a glimpse into the snowfall research planned as part of the Global Precipitation Measurement (GPM) mission. GPM Deputy Project Scientist, Gail Skofronick-Jackson, reveals the capabilities of the satellite's new sensors, which, through increased sensitivity, will help to overcome the challenges associated with measuring snowfall from space.

This article explains the role that the ocean- and the effect of ocean warming- plays in determining the temperature differences between the North and South Poles. The article is part of the Climate Kids website, a NASA education resource featuring articles, videos, images and games focused on the science of climate change.
